CORN-PLANTER.

SPECIFICATION forming part of Letters IPatent No. 649,579, dated May 15,1900.

Application filed October 6 1899. Serial No. '732,828| (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES E. JACKSON, a citizen of the United States,residing at Rockford, in the county of WVinnebago and State of Illinois,have invented certain new and useful Improvements in Corn-Planters, ofwhich the following is a specification.

The object of this invention is to actuate the seed-slide by springforce, the spring force being accumulated by the supporting-wheels andliberated by a checking-wire.

In the accompanying drawings, Figure 1 is a plan View of a corn-planterembodying my improvements. Fig. 2 is a plan view of the springarrangement in the position it occupies after the first check has takenplace. Fig. 3 is a plan view of the spring arrangement in the positionit occupies after the second check has taken place. Fig. 4is anelevation of the runner-frame as seen from the rear. Figs. 5 and 6 aresections on dotted line a, Fig. 1, showing the means for storingspring-power. Fig. 7 is a section on dotted line b, Fig. 1. Fig. 8 is anend elevation of one of the trips for releasing the seed-slide; and Fig.9 is a section on dotted line a, Fig. 1.

Upon the axle 1 are mounted the supporting-wheels 2, and a frame 3 issupported by the axle. The forward end of the frame is pivotallyconnected to a transverse bar 4, forming a part of the runner-frame,having its ends 5 bent forward and connected by braces 6 to the forwardend of the runners or furrow-openers 7. A transverse brace 8 connectsthe forward ends of the runners, and to this brace is connected a frame9, extending rearward beyond the pivotal connection between therunner-frame and wheel-frame.

Seedboxes 10 are supported by the runnerframe, and a seed-slide llactuates the seed cups and valves in the boxes, which I have not deemednecessary to show. Each end of the seed-slide has two vertical holes 12and 13. A tongue 14 is connected to the runner-frame in any suitablemanner.

To the rear face of the bar 4 are secured two brackets 15, which supporta shaft 13 in a manner to permit it to revolve. Upon one end of thisshaft is located and secured a sprocket-wheel l7, and a linkeddriving-chain 18 connects this sprocket wheel with a sprocket-wheel10,seoured'to the axle .1, so

that as the supporting-Wheels 2 revolve its motion will be imparted tothe shaft 16. To this shaft 16 is secured a two-armed bar20, having itsends in hook form. A curved bracket 21 is supported by the bar 4 and hasan overlapping portion 22 at its outer edge. An arm 23 has a pivotalconnection with the bar 4 and has one end 24 curved and its other end 25bent at right angles thereto and overlying the seed-slide. A spring 26connects the seed-slide and pivot of the arm 23. A roller 27 is locatedon the upper face of the seed-slide, and a pin 28 depends from its underface. To the under face of the bar 8 of the run nor-frame is secured abracket 29, and to its free end is pivoted an arm 30. The upper end ofthis arm has a connection with the arm 23 by a link 31. To the centerportion of this arm is pivoted an arm 32, its free rear end 33 being inhook form and guided in the loop 34, depending from the lower edge ofthe bar 4. A coiled spring 35 has a connection with the center of thearm 30 and with the tongue 14.

To the front face of the bar 4 is pivoted a bell-crank lever 36, Fig. 1,having its horizontal arm weighted, and a stop 37 limits the I downwardmovement of the horizontal arm.

A pin 38 extends forward from the vertical arm of the bell-crank lever.The forward end extension 5 of the bar 4 supports means which areoperated by the check-wire, both ends supporting similar means. To eachend extension is secured a bracket 39, through which the end of theseed-slide passes andis guided. The upper portion of the brackets havean opening 40. To the forward end of the end extensions is pivoted anarm 41, its rear end guided in the opening 40. Aroller 42 is sup portedby the arm 41 about midway of its length. A rod 43 is guided in verticalopenings in the bracket 39 and passes through the rear end of the arm41. A pin passes through the rod 43 just above the arm 41, and a coiledspring 44 surrounds the rod between the pin and the upper end of thebracket 39, so that the pressure of the spring will be downward on thepivoted arm 41. A roller 45 is supported by the end extensions inadvance of the roller 42, supported by the pivoted arm 41. A rock-shaft46 is supported by the end extension and to the rear end is rigidlysecured an arm 47, its upper end being bev-' eled. This rock-shaftsupports a roller 48, revolving on a horizontal pivot and located at therear of the roller 42, and supports the knot on the wire in passingbetween the rollers 42 and 48, and will raise the pivoted arm 41,suificient to raise the rod 43 clear of the hole in the seed-slide, andafter the knot has passed the arm will descend.

As the machine passes over the ground a rotary movement will be impartedto the twoarmed bar 20, and when the parts are in the position shown atFigs. 3 and 5 the closed end 53 of the arm 32 will rest in contact withthe front edge of the arm 30, which will hold the hooked end 33 of thearm 32 in the path of the revolving two-armed bar 20, and the hooked endof the bar will engage the hooked end of the arm, and as it revolves itwill move the arm rearward against the action of the spring 35 until itassumes the position shown at Fig. 6, and when the revolving bar becomesdisengaged from the arm the arm will drop into the position shown indotted lines, Fig. 6. WVhen the arm 32 is moved bodily rearward, it willmove the arm 30 on its pivotal connection with the bracket 29, and itsupper end will move rearward and through the link 31. The arm 23is-moved on its pivot until it assumes the position shown at Fig. 1. Thepivoted bell-crank lever 36 by reason of its weighted end will fall inthe path of the curved arm 24, so that when the arm 32 has becomedisengaged from the bar the force of the spring 35 will move the curvedend 24 of the arm 23 against the vertical end of the bell-crank lever,thereby forming a stop.

The seed-slide is held against movement by the rod 43, at the left-handend of the machine, passing through the vertical opening 13 in the slideand into the vertical opening in the bracket 39. The rod 43, at theright-hand end of the machine, is held above the seedslide by the arm 47at that end holding the pivoted bar 41 elevated, while the arm 47, atthe left-hand end of the machine, is out of the path of the movement ofthe pivoted arm 41 at that end. It will be noticed at Figs. 4 and 9 theseed-slide is at the end of its movement to the left hand and that thespring 26 is extended. If the knot of the checking-wire should raise theroller 42 and pivoted arm 41 at the left-hand side of the machinesuflicient to clear the rod of the hole in the seed-slide, theseed-slide would be moved lengthwise to the right hand by the action ofthe spring 26 until the hole 12 in the seed-slide comes under the rod,when the rod will drop into the hole and hold the slide from furthermovement, and this movement of the slide will cause a hill of corn to bedropped from both seedboxes, will also carry the roller 27 near to theend of the arm 23, and the pin 28, depending from the under face of theseedslide, will engage the pin 38, extending from the bell-crank leverand will move the bellcrank lever sufficiently to release the pivotalarm 23, when it will assume the position shown at Fig. 2.

of the seed-slide the spring 35 will move the arm 23 through the link31, and its end 25 will move in contact with the roller 27 and move theseed-slide into its original position, when the parts will appear. asshown at Figs. 3 and 5, and the rod 43 will drop into the opening in theseed-slide and hold it from moving. As before stated, the two-armed bar20 is constantly rotating, and this last 80 movement of the spring 35will move the arm 30 into the position shown at Fig. 5,.and the closedend 53 of the arm 32 will hold the hooked end of the arm in the path ofthe movement of the two-armed bar 20, which will move the parts into theposition shown at Figs. 1 and 6, which are held against the action ofthe spring 35 by the bell-crank lever acting as a stop to the arm 23.When the spring 35 moves the seed-slide 11 to the lefthand end of themachine, it causes the spring 26 to be extended. Two complete checkingmovements are made each time the power is stored in the springs andabout one-fourth turn of the two-armed bar is necessary to store up thespring-power, and this is accomplished at about eight inches travel ofthe supporting-wheels.

At Fig. 4 it will be seen that the-rollers 48 and 49, supported by therock-shaft 46 at the left-hand end of the machine, are held in position,so that the knot of the checking-wire can raise the rod 43, while thelike rollers at the right hand end of the machine are dropped. By meansof the hand-lever 51, pivotally connected to a bracket 50, having aconnection with the arms 47 by the links 52, the rollers 48 and 49 atthe right hand of the machine may be raised and those at the lefthandend dropped, and the rod 43 at the end of the machine in which therollers are dropped is held free of the seed-slide, and in dropping therollers the checking-wire is liberated and the other rollers placed inposition to receive the wire, and it will be noticed that the rod inengagement with the seed-slide is not raised therefrom by the arms 47until the rod at the other end of the machine has engaged theseed-slide. This is necessary in order that the seed-slide will be heldagainst movement when relieved of the checking-wire.
